Explainer https://github.com/w3c/webtransport/blob/main/explainer.md https://github.com/w3c/webtransport/issues/35 Specification https://www.w3.org/TR/webtransport https://streams.spec.whatwg.org/#readablestreambyobreader Summary Support BYOB(bring-your-own-buffer) readers for WebTransport to allow reading into a developer-supplied buffer. BYOB readers can minimize buffer copies, as well as reduce memory allocations. This feature aligns blink implementation with the WebTransport spec (https://www.w3.org/TR/webtransport/#webtransportreceivestream-create). The underlying source of blink::IncomingStream and blink::DatagramDuplexStream are changed to UnderlyingByteSource to support this feature.

WebView application risks This feature doesn’t change the behaviors of exiting APIs. Calling getReader() without options returns a default reader. Debuggability This feature can be debugged with existing DevTools JavaScript debugger. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>? Yes Flag name Requires code in //chrome?
